Abstract

A rear sub-frame structure is provided and used for avoiding impact from road edges and the like and achieving a light weight of a vehicle. The rear sub-frame (12) comprises a cross beam (18) extending at the vehicle width direction. The cross beam (18) is provided with vehicle width end parts (18a) at two sides along the vehicle width direction, and a vehicle width central part (18b) between the vehicle width end parts (18a). The vehicle width central part (18b) is lower than the vehicle width end parts (18a) at the up-and-down direction. The lower surface of the vehicle width central part (18b) is provided with reinforcing parts (22). The reinforcing parts (22) respectively fasten front and rear ends of the cross beam (18). At least a part along the vehicle width direction of the rear end surface of the reinforcing parts (22) is provided with an inclined surface part (30). The inclined surface part (30) is provided with an inclined surface rising toward the rear part of the vehicle.

Description

technical field [0001] The present invention relates to rear subframe construction for vehicles. Background technique [0002] For example, Patent Document 1 discloses a rear sub-frame structure in which a bracket for mounting a suspension device is fixedly installed on a rear cross member on which a cross member is attached to the lower surface of the rear floor of the vehicle, and on the suspension The hook for towing is fixedly installed on the bracket for installing the rack device. [0003] In addition, Patent Document 2 discloses that a suspension beam is provided between the side frames on the left and right sides to support the engine main body, and the suspension beam main body having a U-shaped cross section is provided on the inner surface of the suspension beam main body. There are a plurality of reinforcing ribs extending in the vertical direction. [0004] prior art literature [0005] Patent Document 1: Japanese Publication No. 58-28067 [0006] Patent Doc...
